z claims. (ci. al1-36) This invention relates generally to vises, and inparticular to woodworkers vises, which may be tilted at any angle to thework benchA to facilitate the holding of materials in advantageousposition, and to provide a sturdy implement which is also simple, andeconomical to manufacture.

An object of this invention is to provide a vise having a hinged platefor angular attachment to a work bench.

Another object of this invention is the provision of a vise havingtiltable jaws, and in which the movable jaw can be adjusted by theregular screw, or can be released, and slid bodily in or out relativelyto the rear jaw by means of a split-nut mechanism.

Still another object of the invention is the provision of novelreleasing means for the split nut, to enable the movable jaw to slidefreely.

The foregoing and other objects and advantages will appear more fullyhereinafter from a consideration of the detailed description whichfollows, taken together with the accompanying drawings as illustrated byway of example, in which:

Figure 1 is a vertical longitudinal sectional view of the preferredembodiment of the vise.

Figure 2 is a horizontal sectional view of the vise.

Figure 3 is'a vertical, longitudinal sectional view of the vise similarto Fig. 1, but shows the split-nut release mechanism in nonoperativeposition.

Figure 4 is an elevation of the outer face of the movable jaw.

Figure 5 is a side elevation of the vise positioned vertically, the jawsbeing disposed parallel to the top of the work bench.

Figure 6 is a side elevation similar to Fig. 5 but showing the vise jawsdisposed at right angles to the top of the work bench, and

Figure 7 is a transverse vertical sectional view taken on the line 7-7of Fig. 6, showing the rear jaw in elevation and showing the means forretaining the jaws in rotational engagement with the vise frame, butomitting the visesupporting lugs and hinge plate.

Similar reference numerals designate corresponding parts in the variousfigures of the drawings.

Referring to Fig. 1, the preferred embodiment of the vise as illustratedcomprises a frame 1, a supporting plate 2, adapted to be secured to awork bench 3, as shown in Figs. 5 and 6, said plate having a terminalear 4 to which the vise frame is pivotally attached through the mediumof a lug 5, and a pivot pin 6.

The frame 1 is tubular and is provided at one end with a circular ilange7 to which is rotatably attached a rear jaw member 8, held in place bysemi-circular plates 9 secured to the jaw 8 adjacent its outer edge, thejaw thus being adapted to rotate on flange 7. The rear jaw 8 is formedwith a boss 11, and is rotatably mounted in the tubular frame 1, theframe having a shoulder 12 to resist the end thrust of the jaw 8.

A movable jaw member 13 having spaced guide bars 14 extending from itsinner face through a central opening y in the rear jaw, is slidablyconnected with the frame and the rear jaw member 8 by means of vabearing 38. An adjusting feed screw 15 extending axially of the tubularframe, is rotatably mounted in the jaws 8 and 13, said screw having ahead 16 rigidly attached to its outer end by a pin 17, in which ispositioned the usual slidable cross handle 18. The head 16 abuts againstthe outer face of the movable jaw 13, and both jaws 8 and 13 areprovided with reinforcing ribs 19 and 20, respectively. At the end offrame 1, remote from the jaws, the screw 15 engages a split nut 21having the same gauge threads as those of the screw to actuate themovable jaw, and at the sa'rne time acting as a second bearing for thescrew. As will be seen from the drawing in Fig. 1, the split nut 21 isslidably contained in an annulus 22, which is provided with rearwardlydivergent, opposite inner walls or surfaces 23, on which outer forwardlyconvergent walls or surfacesof the split nut slide, the split nut beingin two sections and the sections having a wedge-shaped conigurationcorresponding with that formed by the opposite inner walls of theannulus 22. I

The annulus 22 is rotatably secured in the tubular frame 1 by means ofset screws 24 engaging a groove 25 in the annulus, the latter bearing ona shoulder 26 in frame 1.

To release the split nut from engagement with the screw 15, a releaseframe is provided, saidv frame'c'omprising a sleeve element having aflange 27 having openings through which the guide bars 14 extend, and aboss 28 surrounding the screw for engaging the split nut upon slidingmovement of the release frame. A handle 29 is secured to the ilange ofthe release frame for manual actuation to release the split nut 21, andadjacent the opposite end of the nut, a keeper 30 surrounds screw 15 andis slidably mounted on guide bars 14 to prevent the parts of the splitnut from falling out of place when disengaged from the screw 15. ThesleeveV element and the keeper are connected to move in unison by meansof bars 31, which are positioned adjacent to, and slide on the guidebars 14, as clearly illustrated in Fig. 2. In Fig. 3 the construction ofthe split nut in the released position is clearly illustrated, and needsno further description.

There is a cutaway portion 32 in the frame 1 to enable the operator tograsp the handle 29. In Figs. 5 and 6, the pivoting arrangements areshown. In Fig. 5, the jaws are disposed parallel to the top of the workbench 3, while in Fig. 6, the jawsy are disposed at right angles to thetop of the Work bench, dotted lines showing the position of the jawsafter they have been rotated around the axis of the tubular frame,through an angle of ln the construction of the pivoting arrangement, itwill be seen that the supporting plate 2 is secured to the work bench 3by counter-sunk set screws 33, or the equivalent, and the frame 1 ishinged to the plate 2, through the medium of the pivot pin 6. A bracket34 is secured to the under side of the Work bench 3, and a slotted bar35 is piv-oted thereto. A threaded pin 36 is attached to the frame 1,Iand is adapted to slide in the slot of bar 35. The pin 36 is engaged bya clamping handle 37, so that the vise may be clamped in any position ofangular adjustment, and since the jaws can also rotate on the frame, avirtual universal adjustment of the vise may be obtained.

Often it is necessary to hold articles that Iare tapered transversely tothe jaw members, and in order to provide proper bearings for sucharticles the movable jaw 13 is pivotally mounted on the end of bearing38 by means of pins 39. The opposite sides of the bearing are rounded asat 40, in Fig. 2 to permit pivotal movement of the jaw 13. To secure thejaw 13 against pivotal movement pins 41 are carried by the jaw whichengage in grooves 42 formed in the bearing, which pins are removable.

From the foregoing it will be seen that I have pro 3 Yidsdta visevithidt is ;\{ery. ,easy5to manipulate; is capable of' wide rvariatonsofadjustment, and is both simple and economical to manufacture.
